Purposes of Transactions

On January 31, 2014,

debtor issued (i) a promissory note to the Trust in connection with a loan made pursuant to such Loan and Forbearance Agreement and (ii) an amended and restated
promissory note to Lee which replaced certain promissory notes previously issued to Lee. The Trust and Lee loaned additional amounts
to Keffi VI and another debtor in August 2014 pursuant to a demand promissory note.

The obligations
of Keffi VI and the other debtor under the notes issued to the Trust and Lee were secured by, among other things, a pledge of the
Ordinary Shares of the Issuer owned by Keffi VI. In connection with such pledge, Keffi VI, Lee, the Trust and JPMorgan Chase Bank

solely the orders of Lee and the Trust concerning the account in which the pledged Ordinary Shares are held. On January 19, 2016,
following a default under the Loans, Lee and the Trust delivered a Notice of Exclusive Control to the Intermediary which gave Lee
and the Trust the right to direct the vote and disposition of the Ordinary Shares of the Issuer held in the account.
